  Neuroplasticity is an important factor for upper-extremity stroke rehabilitation, yet the amount of neuromodulation achieved with an acute session of motor practice is not fully characterized. The objective of this study was to determine how engaging in isometric motor practice acutely influences motor control, dexterity, and neuromodulation. Thirteen healthy controls and 5 stroke survivors participated in 2 separate experiments. Assessments [Box and Block Test (BBT), force steadiness, Transcranial Magnetic Stimulation (TMS)] were completed immediately before and following motor practice. Two force steadiness trials were completed at 10 and 20% of the maximum voluntary contraction (MVC). The TMS outcome included an average of 12 suprathreshold stimulations with motor evoked potentials (MEP) amplitudes recorded. Data were analyzed using paired t-tests .. Read More»
